Ecology
Allosaurus thrives in primeval grasslands and high savannas where megafauna still roam — lost plateaus, forgotten valleys, druid-preserved sanctuaries. It is an apex predator of its niche, hunting dinosaur calves, large mammals, and the occasional adventurer. Solitary by habit, females tolerate one another in calving season; males war over territory. Each adult requires hundreds of square miles to feed. Where allosaurs are present, smaller predators flee or burrow.
Behaviour
An allosaurus is a sprinter, not a stalker. It scents prey on the wind, runs it down across open ground, and bites once — hard. If that fails, it rarely commits to a second attempt and moves to easier targets. It is intelligent for a beast: it learns hunting routes, recognizes traps after one experience, and avoids fortified settlements. It rests by day in shaded gulches and hunts at dawn and dusk.
Origin
Druidic tradition holds that allosaurs are the children of an ancient world-shard preserved by Chronepsis or by sundered timestreams. Some scholars argue they were transplanted by genie merchants or by reckless conjurers. Their bones are common in glacial deposits, suggesting they once roamed widely. Today, isolated populations persist in fey-touched wilds, druidic preserves, and the elemental Plane of Earth's grass-mantled provinces.
